Sounds like you took the right approach by trying to start fresh. Might try again being diligent about unpairing and disconnecting from all devices and having any other devices turned off. I must admit though if it were me I would likely spring for a TV Connector. They really are a slick device. I’ve seen them for as low as $150 and if you could find a way to buy one from Costco, they have them for $100. Good luck and keep us posted.
